Carotid elasticity measurements

摘要: The morphology of blood vessels, as expressed by (lumen) diameter and wall thickness, depends on the forces exerted it. To what extent balance interaction between shear stress transmural pressure their absolute values are contributing to adaptation arteries is still a matter debate, mainly because currently no adequate non-invasive measurement methods available answer these questions comprehensibly. However, recent ultrasound developments allow transcutaneous assessment morphological functional characteristics arteries. latter depend elasticity can be derived from relationship time-dependent cyclic vessel resulting pulsatile strain, i.e. relative increase in circumference. This chapter will discuss various techniques quantify elastic behavior carotid artery combination with its morphology, applicability limitations.
